I've found that whatever town you happen to be in if you can locate a skatepark you can probably find some herb. Just strike up a convo or two and through in a "Hey man, you know where to get any bud?" I'm talking a public park of some sort. The odds in a pay to skate "skating rink" type of environment may be a little different.

Or I'm sure there has got to be a hippy-esque part of town, road, street-corner, shop. That would be a good place to hangout.

Or just go make three new friends, one of them should be able to help you.
